BEER-PUMPING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 435,694, dated September 2, 1890. Application filed July 3, 1889. Serial No. 316,472. (No model.)

To all whom it may concern.-

Be it known that we, FRANK HERMANN and JOHN RICHARD BERNARD J ANss N, both citizens of the United States, residing at Sterling, in the county of Vhiteside and State of Illinois, have invented certain new and useful Improvements in Beer-Pumping Apparatus; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Our invention has reference to improvements in beer-pumping apparatus, and has more special application to the addition or attachment of a reservoir-tank connected directly to the airpum p, in which to store compressed air sufficient at least to force out the contents of one cask of beer, and in the further provision of a filter or purifying-chamber through which the air in being pumped into said cylinder is divested of its impurities. Asthe air is pumped into said cylinder through the clarifying medium the impurities are re moved from the air before the latter reaches the reservoir, and the air-reservoir being lo cated within the ice-box the air in suchreservoir will be kept at a low temperature, so that in its transmission into the cask it will not have the effect of lowering the temperature of the contents of the cask, as is the case where the air is directly drawn from the heated and vitiated atmosphere of the room.

In the drawings, Figure 1 is a side elevation of an apparatus involving our invention, the side of the ice-box being removed in order to show the same. Fig. 2 is adetail, in section, of the purifying-chamber attached to and com- Inunioating with the air-cylinder.

A is the ice-box, in which are seated the casks B B.

O is the intermediate fioor of the ice-box, on which the ice is placed in-the usual manner, and D is the chamber of the ice-box under the floor C, which is kept at a low temperature by reason of the ice above said floor.

E is the air-compressing reservoir, suitably suspended beneath the floor 0.

F is the pump-cylinder, in which is seated the usual valve, and within which reciprocates the piston G. The piston G is operated by means of the lever H, fulcrumed on the outside of the ice-box upon the stud H, the piston G having its outer end pivotally attached at any intermediate point G on said lever.

J is an open-ended purifying-chamber attached to the side of the air-reservoir E, and having communication with the pump-cylinder F by means of the hose J, suitably connected at its outer end to the short tube J", provided with stop-cock J and attached to and communicating with the inner end of the cylinder F, and having its inner and inserted centrally in the cap K of the chamber J. The chamber J is. cylindrical and rigidly seated .on the side of the reservoir E, and has communication therewith through the perforated partition L, placed across said chamber J at the point of its communication with said reservoir E. The cap K of chamber J is also cylindrical and hollow, and is adapted to project within the chamber J, and is provided peripherally with threads K, adapted to engage conforming threads on the inside of the walls of the chamber J. The inside of the walls of the cap K are also threaded, and the inner cap M is also cylindrical and hollow, and, having peripheral threads adapted to engage the inner threads of the cap K, is screwed into the inner end of the cap K. The inner end of the cap K and outer end of cap M are both open, and across the head or inner end of the cap M is placed the metallic sieve l\' The cap M is filled with any purifying-mixture R, preferably soda, is then screwed into the inner end of the cap K, and the latter screwed into the chamber J, as shown in Fig. 1. The cap K and the inner cap M can be readily removed at any time for the purpose of changing the purifying-mixture,

The compressed air is communicated from the reservoir E to the casks B by means of short hose-connections N N, attached, respectively, to the tubes N, formed on the lower side of the cylinder E and communicating therewith. Stop-cocks N are seated on the tubes N for the purpose of temporarily cutting off the escape of the air from cylinder E in changing the casks. By having a proportionate number of the tubes N such num ber of hose N can be coincidently used as may equal the number of casks in the icebox, and by means of stop-cocks N" the air can be diverted into or excluded from any number of casks.

O O are the beer-exit tubes or hose communicating from the casks to the oxterna faucet P. An ordinary automatic valve opening inward is seated in the short tube 2, which connects hose N with the vertical tube 3, inserted in the cask l3, and prevents the beer when rising through the'tube 3 from passing into the hose N and compels it to pass out through the tube 0. A faucet 4, for convenience in changing tubes 3, is seated in the upper portion of the tube 3. That portion of the tube 3 which enters the head of the cask is provided with threads 5 for greater security and tightness. A tube 6 communicates at its inner end with the cylinder F,

and is projected outward through the front wall of the ice-box A, and communicates at its outer end with the usual gage or register 7, adapted to indicate the amount of pressure within the cylinder F.

\Vhat we claim as our invention, and desire to secure by Letters Patent of the United States, is

In combination with an air-pump and a compressing-air reservoir, the purifying-chamber J, rigidly seated in the wall of said reservoir and containing a hollow cylindrical cap K, communicating through its outer end with the hose of said pump and adapted to project within said chamber J, and provided peripherally with threads K, adapted to engage conforming threads on the inside wall of chamber J, and a hollow cylindrical cap M, of less diameter than the cap K, screwed into the inner end of the cap K, and the purifyingmixture R, placed within the cap M, the inner end of the cap M being closed with the metallic sieve M, substantially as shown, and for the purpose described.

In testimony whereof we afiix our signatures in presence of two witnesses.
